Features
ZL50212 has nine Echo Voice Processors in a
single BGA package. This single device provides
288 channels of 64 msec echo cancellation or 144
channels at 128 msec echo cancellation
Each Echo Voice Processor has the capability of
cancelling echo over 32 channels
Each Echo Voice Processor (EVP) shares the
address bus and data bus with each other
Fully compliant to ITU-T G.165, G.168 (2000) and
(2002) specifications
Passed all AT&T voice quality tests for carrier
grade echo canceller
The ZL50212 provides more than 63% board
space savings when compared with the nine Echo
Voice Processors packaged devices
Each EVP has a Patented Advanced Non-Linear
Processor with high quality subjective performance
Each EVP has protection against narrow band
signal divergence and instability in high echo
environments
Each EVP can be programmed independently in
any mode e.g. Back-to-Back or Extended Delay to
provide capability of cancelling different echo tails.
Each EVP has 0 to -12 dB level adjusters at all
signal ports (Rin, Sin, Sout and Rout)
Each EVP has the same JTAG identification code
Applications
Voice over IP network gateways
Voice over ATM, Frame Relay
T1/E1/J1 multichannel echo cancellation
Wireless base stations
Echo Canceller pools
DCME, satellite and multiplexer system
Description
The ZL50212 Voice Echo Canceller implements a cost
effective solution for telephony voice-band echo
cancellation conforming to ITU-T G.168 requirements.
The ZL50212 architecture contains 144 groups of two
echo cancellers (ECA and ECB) which can be
configured to provide two channels of 64 milliseconds
or one channel of 128 milliseconds echo cancellation.
This provides 288 channels of 64 milliseconds to 144
channels of 128 milliseconds echo cancellation or any
combination of the two configurations. The ZL50212
supports ITU-T G.165 and G.164 tone disable
requirements.
